Stock Exhaust Crossover Clamp Size?

[DirtyErnie]

My search-fu is failing me

What size is the clamp for the stock exhaust crossover? I need to add at least one more cent to my Amazon shopping cart to get free shipping, and I need a clamp that wasn't shipped with eBay Junkyard exhaust.

It's about 3/4 to 7/8"s wide if that helps. I kinda thought those clamps stayed with the crossover, almost integrated.

No, they're free clamps, cuz this one fell off and is missing. There's four pads, spaced 90 degrees apart, on the petals where the right side slides into the left side. all I know is a 1.75" clamp is too big. 1 1/2?

This is for the '80-84 Special, that may be important here.

Special exhaust is Special exhaust through the years from what I can tell.
I'd probably put a hose clamp or two on and call it done......as long as it didn't leak.

Hi Ernie,
just for you, I crawled under my Heritage Special and measured the bastard.
The split cuff on the end of the leftside crosspiece that the clamp fits over is 1-5/8" OD.
Don't forget that the joint between the two crosspipes needs a mebbe 1/8" wall crush sleeve to fill the gap.
You'll need a new one because they only work once.
My crosstube is squeezed by an ordinary hose-clamp that seems OK but if I were to remake that joint I'd use
a wider clamp, the ~$5 all stainless steel nut'n'bolt one from a hydraulics supply store.

Hi Ernie,
it's called a T-bolt hose clamp, got 'em all over my XS11's replacement exhaust
